Be it known that l, JOHN HENDERSON, a" citizen of the llnited States,residing at Waterbury, in the county of New Haven and State of.Connecticut have invented a new and useful improvement in SteamlilelaTumbling-Barrels, of which the following is a specification.

This invention relates generally to tumtiling barrels and moreparticularly to a tiltahle rotary barrel, and the object of theinvention is to provide a steam jacket in connection with a tumblingbarrel of this oil said barrels.

Another object of the invention is to proride for the introduction ofsteam during the same time eliminate "back pressure,

llmother object oi" theinvention is to pro vide a steam heated tumblingbarrel in which live steam is introduced and from which water oilcondensation is discharged at definite intervals.

With these objects in view the invention consists in the novel leaturesoi construction, combination and arrangement all of which willv be fullydescribed hereinafter and pointed out in the claims.

in the drawings forming a part of this specification: Figure 1 1s aperspective view of a tumbling barrel embodying my invention, a portionot the barrel bein broken away. Fig. Q is a vertical sectiona view takenthrough the barrel and a hollow shalt extending intothe bottom of thesame. Fig. 3 is a :lace view of the inner side of scoop for collectingand discharging the water of condensation. Fig. 4 is a detail endview.Fig. 5 is a detail sectional View showing the manner of connecting thesteam pipe to the cadet a hollow shaft. lii 6 is a detail view ol thecollar and disc arge pipe, and Fig. '2 is'a plan view of the collar. llncarrying out my invention I employ struction of bottom A, said bottomhein usually flanged as shown in Fig. 2 and rigidly attached to the saidflanged bottom is a supplemental bottom or plate ll provid ing a closedcircular space at the rear or bottom end ol the tumbling barrel. Thebarrel is provided with the usual construction of bevel gear l3 androcks upon a trunnion D, it being understood that the barrel 'is bothrotatable and tiltable and in the drawings l have illustrated means forraising and lowering the barrel, but no claim is made thereto in thisapplication. A hollow shaft E is passed centrally through the hub oitthegear C and communicates at its inner end with the closed space at thebottom of the tumbling barrel.

l indicates a steam pipe which is con' nccted to the trunnion D, saidtrunnion be ing made hollow so that steam can be introduced thereintoand a steam pipe G leads from this hollow trunnion to the rear end ofthe hollow shaft E, said steam pipe being connected to said hollow shaftthrough the medium of a coupling memberG', which entersthe rear end ofthe hollow shaft and is held in place by means of a gasket ll, securedby means of screws H, a packing ll bein interposed between the shaft andcoupling connection and a similar arrangement may be employed where thesteam pipe enters the hollow trunnion, this construction making thesejoints steam tight.

lfnstead of a separate coupling G as shown in Fig. 1 it is-obvious thatthe rear end of pipe G can be bent or shaped'so as to enter the rearendoi the hollow shaft and the gasket and packing will be exactly the sametrunnion, pipe Gr and hollow shaft into the I closed space or steamjacket at the bottom or rear end of the tumbling barrel therebythoroughly heating the contents of said barrel and by the employment ofthe hollow trunnion and shaft and making the steam communications in themanner heretofore described it is obvious that steam can be introducedduring both the rotating and tilt ing operations of the barrel. Aportion of the steam will in due time be condensed and in order toremove this water of condensation I provide a combined collecting anddischarging scoop ll, comprising the curved or circumferential member l,which is in the nature of a tube attached to the inner face of the.bottomor plate B, and the radial member I which extends from thecircumferential member l nearly to the plate B. This collecting scoopcomposed of the memhers I and l is connected to the plate B by means ofsuitable clips such 'as shown at P. The inner end of the radial ,member1 communicates with an opening B produced in the plate B, which openingin turn communicates with a passage or bore K produced in the hub of thegear 0, said passage or bore K being of the shape indicated in Fig. 2and thereby providing a discharge outlet for the water of condensation,which is collected in the member I at each rotation of the barrel andconveyed through the member 1 to the opening B and passage K andsurrounding the .hub of the gear is a collar L having an opening M whichopening is adapted to register with the passage or opening K once ateach revolution of the barrel so that the water of condensation can bedischarged through said' opening M into the curved pipe N which leadstherefrom, said pipe extending downwardly toward the floor where thewater can be discharged. The collar L serves as a cut-off to close theopening K during the remaining portion of the revolution. This collar Lis formed with an inwardly extending fiange L'- which snugly fits thehub of the gear and prevents the escape of .any of the' water. The steamjacket is provided with a blow-off cock A which is usually opened whenthe device is first started. 7

In operation the tumbling barrel is sup ported and operated the same astumbling barrels in general use and during such operations steam isconveyed to the steam jacket at the bottom or rear end thereof throughthe pipe F, hollow trunnion D, pipe G and hollow -shaft E. The steamentering the jacket quickly heats the contents of the barrel andinasmuch as the barrel is rotating it willbeunderstoodthat any water ofcondensation accumulating in the bottom portion of the steam jacket willbe scooped up in the curved circumferential member I and carried intothe radial member 1 upon the upward turn thereof and this water ofcondensation is discharged through the opening or passage K produced inthe hub and the parts are so positioned with reference to the collar Lhaving the opening N that once at each revolution the water collected orscooped from the lower portion of the steam jacket will be dischargedthrough the pipe N and during the balance of the revolution thedischarge openings are cutoff.

By means of a steam heated tumbling barrel constructed as herein shownand described I am enabled to heat the contents of the tumbling barrelwhile being operated upon and at the same time I eliminate the backpressure. f

It will thus be seen that I provide a sim ple and efiicient improvementcapable of carrying out all of the objects hereinbefore referred to.

What I claim is 1. A tiltable rotary tumbling barrel having a steamjacket, a collector arranged in said jacket, a hollow. shaft leadinginto said jacket, a gear mounted upon said shaft, the hub thereof havingan opening communicating with said collector, a collar surrounding saidhub, and having an opening therein adapted to register intermittentlywith the said opening in the hub, a hollow trunnion and steam connectionfor said trunnion and hollow shaft as set forth.

2. A tiltable rotary tumbling barrel having a steam jacket, a collectorarranged in said jacket, a hollow shaft leading into said jacket, a gearattached to said barrel, and mounted upon said shaft,-the hub of saidgear having an opening communicating with said collector, steamconnections for the shaft to supply live steam,.and means connected withsaid gear for carrying oif the water of condensation. I

3. A tiltable rotary tumbling barrel having a steam jacket, a collectorarranged in said jacket, a hollow shaft leading into said jacket, :1gear attached to bottom of barrel and mounted upon said shaft, said gearhaving a passage in its hub communicating with the inner end of saidcollector, a collar surrounding said hub, said collar having a singleopening through which condensed steam escapes, and steam connections forsupplying the hollow shaft with live steam as set forth.
